1、Designation: C76 15C76 15aStandard Specification forReinforced Concrete Culvert, Storm Drain, and Sewer Pipe1This standard is issued under the fixed designation C76; the number immediately following the designation indicates the year of originaladoption or, in the case of revision, the year of last
2、revision.Anumber in parentheses indicates the year of last reapproval.Asuperscriptepsilon () indicates an editorial change since the last revision or reapproval.This standard has been approved for use by agencies of the U.S. Department of Defense.1. Scope1.1 This specification covers reinforced conc
3、rete pipe intended to be used for the conveyance of sewage, industrial wastes, andstorm water, and for the construction of culverts.1.2 This specification is the inch-pound companion to Specification C76M; therefore, no SI equivalents are presented in thisspecification. Reinforced concrete pipe that
4、 conform to the requirements of C76M, are acceptable under this Specification C76unless prohibited by the Owner.NOTE 1This specification is a manufacturing and purchase specification only, and does not include requirements for bedding, backfill, or therelationship between field load condition and th
5、e strength classification of pipe. However, experience has shown that the successful performance of thisproduct depends upon the proper selection of the class of pipe, type of bedding and backfill, and care that installation conforms to the constructionspecifications. The owner of the reinforced con
6、crete pipe specified herein is cautioned that he must correlate the field requirements with the class of pipespecified and provide inspection at the construction site.NOTE 2Attention is called to the specification for reinforced concrete D-load culvert, storm drain, and sewer pipe (Specification C65
